Using Rankx to get a dynamic scheduling matrix (how to)

Hi all, 

I recently had a piece of work to do where I had to build a scheduling matrix for a customer. I had to rank entities and then allocate them based on rank to a specific day of the week. I solved this using what to me was a rather elegant solution, so I decided to document it (mostly for my own purposes since I may need to do something similar in the future). 

Anyway, if you have any interest in seeing how I solved this problem, you can check out the  YouTube  video I created. 

I hope it helps someone at some point.
